For a S550 Manual Transmission (3.31 Stock Gear) with the Ford Performance Supercharger 670 HP. What Gear you recommend? 3.55 or 3.73? I only use the car for fun and 201 meters races with M/T 28" Drag Tires, highway revs no matter for me
For drag racing use the 3.73.

Do you carry the 3.31 gear set? Perhaps I'm missing it on the website. I have a 2017 GT PP with stage 2 whipple. The current 3.73 gears make street tires worthless in 1st and 2nd.
3.31 are not currently available.

I have heard some in the SC community suggest this swap to help with traction. I have the 3.73 pp setup with a roush SC and am destroying 305/35/20s. Does having 625 to the wheels change your "not really" answer on this swap? Any experience?
As power increases, the need for a longer rear gear becomes a thing. 3.73s are typically way too aggressive on a 600+hp car. 3.55s will help slightly but a lot comes down to throttle control and mastering the art of slipping the clutch.

I have the performance pack 373 gears any advantages in putting the 355 in instead?

Will the work on a 2015 ecoboost mustang with a automatic transmission with 331 gears ?

Can I change the performance pack 3.73s to this 3.55. The 3.73 is a Torsen.

WHY WONT THIS WORK WITH A FACTORY REAR END WITH 3.15RG . THEY BOTH USE THE SAME HOUSING FR3Z-4310-A
The 3.15 housing is cast aluminum housing, you would have to switch to the cast iron housing to change gears ratio.

I have been told that the 3.55 Ring and Pinion will fit my 2015 Mustang GT with the stock 3.15 gears if I also replace the limited slip differential Your website simply says the 3..55 gears won't fit. Can you clarify?
You are correct, the whole differential will need replaced to run the 3.55 gears. Take a look at this part for a complete solution: http://www.cjponyparts.com/ford-racing-differential-housing-iron-loaded-with-3-55-gears-automatic-2015-2016/p/M400188355/
